HAY-RAKE.

SPECIFICATION forming part of Letters Patent No. 394,64'7, dated December 18, 1888.

Application filed April 20, 1887. Serial No. 235,562. (No modeli) To all whom, it may concern:

Be it known that I, PERRY D. IIARDY, a citizen of the United States, and a residentof Northampton township, in the county of Summit and State of Ohio, have invented a new and useful Improvement in I-I'orse IIay-Rakes, of whichthe following is a specification.

My in vention has relation to improvements in that class of horse hay-rakes in which the rake-teeth mounted on a frame, hinged on an axle which tnrns forward with the wheels, are raised to dump their load by a ratchet-wheel mounted on said axle and a pawl attached to the frame and arranged to engage said wheel.

The invention consist-s in the construction and arrangement of parts hereinafter fully described, and then specifically pointed outin the claims, due reference being,I had to the accompanying drawing's, formingl apart of this specification.

In the accompanyingI drawings, Figure 1 is a perspective view of my improved rake, the wheels, bumper, teeth, and reversing device being` omitted to avoid confusion of lines; Fig 2, a. vertical central transverse section of Fig. 1 (enlarg'ed) and unimportant parts omitted; and Fig'. 3, a similar section at the line :11.13 of Fig. l, showing the reversing' device and bumper.

It will be understood that the devices illustrated in Figs. 2 and 3 form parts of the same machine, and I have shown them separately merely in order to more clearly illustrate the Operation of the machine and to avoid con fusion.

Similar letters of ret'erence indicate like parts in the different drawings.

The axle A is a metallic rod, which, by ratchet-wheels or other suitable device,turns forward with the wheels. The thills I, hinged to the axle, are provided with three bars, b, b', and D, the second of which supports the whiffletree and the latter the clearing-rods The seat is mounted on a Spring, E, supported on legs c, the front one of which projects beyond the bar 1)',forming' the upper support for the whifiietree.

The tooth-carrying` frame F consists of two parallel bars nnited by suitable fastenings,f, monnted and arranged to rock on the aXle A, the teeth depending from the rear bar.

On the center of the axle a ratchet-wheel,

G, inclosed in a case, II, open at the top and closed at the bottom, in which case a lever, I, is pivoted, which carries a pawl to eng'ag'e the ratchet, and held out of contact by a spring, g. By causing' the pawl to engage the ratchet the frame is swung forward and dnmps the load, when the lever I enconnters the bar Z), releases the pawl, and permits the frame to Swing back.

Thus far the construction and operalion do not differ materially fronr rakes in use, eXcept in the form and construction of the case H and lever I.

In my improved rake the sides of the case H extend beyond the bottom, makingl a semicircular channel with an Opening' into the interior at the point J.

A fiat spring', K, bent to conform to the shape of the channel, rests therein, and its upper end, k, bent inward nearly at a right angle and thence upward for a short distance, enters the Opening,I J ,-engages the edge of the Opening, and constitutes a latch, which prevents the frame swinging,I forward until released, but permits it to swingl backward by sliding;` into the opening J.

The front end of the Spring;I K is attached to the bar b' by an adjustable clamp, l), consisting' of two slotted plate/s with similarlycorrng'ated contiguous faces. The lower end, l', of the lever I extends below the pivot, and is arrangcd to engag'e and release the end l; of the spring' at the same moment ihat the pa-wl enga-ges the ratchet.

Attached to the springI E by a spring, m, is

i a slotted plate, M, resting' over the lever I, so

arrang'ed that when at rest the upper end of said lever projects through said slot, and may swing backward or forward without encountering' the ends of the slot; A chain, n, connects this plate with a treadle attached to the bar b'. By depressing the treadle the plate M is swung' forward and the rear end of the slot eng'ages the hook on the end of the lever I, throws the pawl into the ratchet, and simultaneously releases the spring-latch Ir, thereby causing the frame F to Swing' forward, as hereinbefore stated.

Near the end of the bar is a bearing, p, in which is pivoted a lever, P, having a long and short arni, the former projecting upward and constitutin,I a handle, and the lower IOO hinged to a link, Q, hereinafter described. Opposite this lever, on the bottom of the frame F, is a cast plate, R, having a front projection, r, and a rear projecting hook, rr'.

Hinged to the bar D, opposite the front projecting end, fr, is an elastic bumper, S, of coivled Spring, rubber, or other suitable material, against which the end 7' rests while raking, and which, when the frame swings back after the load is dumped, arrests its motion without shock to the machine.

The link Q consists of a strap of iron of sufficient weight to retain its shape when in use, having' a slot in its outer end and bent, as shown, to avoid the intervening parts of the rake and bring the slotted end about the hook r' in the same manner as the slotted plate M surrounds the lever I, and as the one will be readily understood from the drawings of the other an elevation only is shown.

The slot extends so far back that the hook fr' will not engage its back edge when the frame is swung forward to dump the load. To hold this link Q in position over the hook fr', there is a similar but smaller hook, s, on the back end of the bumper S,whieh rests in a short slot in the link Q, and which practically makes a hinge therewith. i

The weight of the long,` arm of the lever P eonstantly presses the link` Q back, thereby swinging1 the bumper into a horizontal position, as sho wn,which in. turn holds the slotted end of the link over the hook r'. By throwing' the upper end of the lever P back thelink Q ,is drawn forward, swinging' Vthe bulnper S down out of the way of the end r, and by eng'aging the hook r' rocks the frame F backward, bringing the teeth fi under the thillframe, as shown by dotted lines, Fig.

I do not desire it understood that I confine my invention to the exact mechanical construction herein. shown and described; but the semicircular Channel may be, distinct from the ratchet-case, the Spring` Kbmay be round, a bent rod maybe used in place of the slotted plate M, a different form of treadle may be used, the ratchet-case inay be arranged to strike the bumper instead of having` a separate piece for that' purpose, the bumper may swing otherwise than down, and, generally, other modifications clearly falling within the scope of my invention to adapt it to different forms of rakes of the class specified may be adopted.

The essential features of which I claim are- 1. In a rake of the kind specified, the coinbination of the rocking tooth-frame provided with a pawl-lever adapted to engage a ratchetwheel upon the axle, whereby the rake is dumped, the Spring-supported plate M, having a slot within which the pawl-lever swings, a lever for Operating` said plate, a hook-catch secured to the rocking tooth-frame, the carriag'e, alever'attached to said carriage, and a slotted link ,connected with said lever and adapted to engage the hook-catch on the rocking` tooth-frame and swing,` the same backward, substantially as shown 4and described.

2. In a rake of the kind specified, the combination of the rocking tooth-frame provided with a pawl-lever adapted to engage a ratchetwheel upon the axle, whereby the rake is' dumped, the Spring-supported plate M, having a slot within which the pawl-lever swijngs, a lever for Operating said plate, the carriage, a hinged bnmperinterposed between said frame an d carriagfe, and a slotted link adapted to engage both the hinged bumper and the rocking tooth frame and connecte'd with a lever, whereby the'hinged bumper is swung down from between the carriage and the rockingl tooth-frame and said frame simult-aneously swung bacluvard, substantially as shown and described.

In'testimony that I clailn the foregoing I have hereunto set in y hand.
